In between each trade, we disassemble each pair of sunglasses and perform a thorough investigation. If the lenses or frames are scratched or damaged, we replace them with brand new parts.
Next, we clean each disassembled part via an ultrasound cleaner. This cleaning process is effective at both polishing & removing germs (we fill the ultrasound cleaner with soap & water).
Following the ultra-sound cleaning, we re-assemble the sunglasses and perform a second cleaning, again with soap and water.sdfsdf sdfsdf pdf pdf pdf pdf pdf sdfsdf pdf pdf pdf pdf sdf
